Finally! A bluetooth headset that works with both phones!

After what seems like ages, I finally have a headset that works with both my cordless and my cell phone! I've got an AT&T EP5632 and a Motorola Krzr K1 (T-mobile), and all I want to do is have a single headset that I can use with both phones simultaneously. I have that now with the BlueAnt Z9i.

The EP5632 has been hit-and-miss concerning with what it will connect/pair. Unfortunately, the only compatibility list is on AT&T's site, and it's severely lacking. To add to the mess, I can't find enough documentation to figure out specifically what it's not compatible with. The best info I've found simply says it can handle Bluetooth 2.0 with both headset and hands-free profiles; In practice, that's not enough info.

Here's what I've gone through:
  1. Plantronics Voyager 510 - YES. Multipoint. Works with both, but not simultaneous (if on one call, cannot switch to other phone to answer). It was was starting to fail on me about the time of the purchase of the AT&T, so I don't recall much of my experience with it.
  2. Plantronics Voyager 520 - NO. Multipoint also, but will not connect with the EP5632. I like the ear-loop and ear-bud/gel.
  3. Plantronics Discovery 655 - YES/NO. Not Multipoint, but will connect to either phone just fine. (It was a gift, and wasn't known that multipoint was critical to me) Beyond that, the ear-gels' connecton is flimsy/cheap, and the ear-loop is held in place by the ear-gel (Everything almost always comes apart when in my pocket.). It never fits well in my ear, so I don't like to use it. Points for the raised volume buttons, though.
  4. BlueAnt Z9i - YES. Multipoint and it can switch between active calls on each phone. So far, the ear-loop and ear-bud make it feel secure. Unfortunately, there's only 3 buttons on the thing, so there's an overwhelming amount of unintuitive, difficult button combinations to activate the various features.
That reminds me: Is there some secret/unwritten rule somewhere that says a bluetooth headset cannot have more than 3 buttons, but the best is 1? I would have loved to try the Motorola H780 if only because it has a dedicated power switch. More buttons means less unintuitive sequences to remember when operating the headset.

Live Migration between domains

For those of you like me who aren't experts at all things Active Directory (AD) and Hyper-V Live Migration (LM) permissions, it can be enough of a pain to LM a Virtual Machine (VM) between domains that you simply decide to take the VMs offline to affect the move. See, I only tolerate AD because it's required for LM'ing VMs; there isn't a choice. (It's also required for Windows Clusters, but that's a different topic.) But I figured it out. My back-story is that we setup a cluster using Windows 2012 r1 as the AD Domain Controller (DC) and Hyper-V Server 2012 r1 for the VM hosts. Then we decided we wanted to use r2 for the AD DC and Hyper-V hosts. Upgrading Hyper-V was easy. But I found that there's some unresolved Microsoft bug with Windows Clustering when upgrading the AD DC from Windows 2012 r1 to Windows 2012 r2--- clustering simply doesn't work correctly anymore . So we gave up and created a from-scratch Windows 2012 r2 AD DC then made a new cluster...

SqlBulkCopy and the "colid" error

I thought there was a page explaining this somewhere out there on the Internet, but I can't find it anymore. So here's what I re-discovered. When you try to insert the rows from a DataTable and the data in one of the columns of one of the rows is too big to fit into the destination column in the database, you get a SqlException with this error message: "Received an invalid column length from the bcp client for colid N." (Where "N" is a number.) It doesn't tell you which row, and it's a pain to figure out what column to look at. To determine what column it is referring to, you first need to get a listing of all columns in the table, listed in the order as they have been defined in the database. Next, you remove any columns in the list that are not represented in SqlBulkCopy.ColumnMappings (the order of the column mappings is irrelevant). The list that remains is what "colid" is referring to, with the first column corresponding to colid ...

Outlook 2007/2010 Search Folders using email address domain

As of May 2010, the Beta of Outlook 2010 still hasn’t overcome this problem. I’m surprised this glaring omission has been left unfixed. Maybe Outlook is maintained by contractors? I have what I consider to be a simple need. I want a “Search Folder” that shows me all the email related to a particular client. What works well for me is a query that finds any email with the client name in the subject, or any email that involves an email address (from/to/cc) from the client's email domain. Back in Thunderbird, it was simple to setup a rule for this. Outlook can't do it. (I'd go back to Thunderbird, but I have to get calendaring working first.) What doesn't work When you edit the criteria for a Search Folder, on the “Messages” tab, the fields you want appear to be represented, but the way things work is wrong. All the criteria specified must be true, not any; they went with “AND” where I need “OR”. The other problem is that the “From…” and “Sent To…” fields use a “starts-with...
